  "excerpt": "ヤマハ Rn39, Rn40N. Published by MLIT as 1222770 on 14 December 2015. Part: Ｍ／ｔ. What the notice says 変速機において、ギヤの強度が不足しているため、サーキット走行等でスロットルを急全開にして加速しながら変速操作を行うと、当該ギヤに過大な応力が加わることがある。そのため、そのまま使用を続けると、亀裂が生じて破損し、最悪の場合、走行不能となるおそれがある。 Is your vehicle included? Check with your VIN at MLIT , or ask a dealer. This page is an independent copy of the notice, kept so you can see what changed after it was published. It is not the authority, and the authority’s own text is the one to act on. The two passages above are quoted in Japanese because that is the language the ministry published them in. This site keeps the wording a register had when it was read, and does not translate a safety notice. Source: Ministry of Land, Infrastructure, Transport and Tourism website （出典：国土交通省ウェブサイト）, used under the Public Data License 1.0. This site gathered the record, grouped it by notification number and set it in English around the ministry's own words; the notice itself is unaltered. CarsMultiverse is not the ministry and not a safety authority. To act on this notice, use the ministry's own document . The Japanese register on this site ヤマハ is named on 181 notices in the copy of MLIT’s register held here, of which these are the nearest to this one in time. 2104811 · 10 November 2015 · Ebj-Se44j, Ebj-Se53j · 駆動力伝達部 2104812 · 10 November 2015 · Ebj-Se53j · エンジン本体 1136600 · 9 October 2015 · Jbk-Rg10j, Ebl-Rh07j · ハンドル 1135870 · 16 June 2015 · Jbk-Sg20j, Jbk-Dg15j · 発電機 1135280 · 24 March 2015 · Jbk-Rg10j · 配",
